Orchowek Wastewater Treatment Plant, Włodawa, Poland (Closed)

Orchowek is a former wastewater treatment plant located in Włodawa, within the województwo lubelskie region of Poland. The plant was designed with a capacity of 2549.00 and provided primary treatment before its closure. As a closed facility, it no longer processes wastewater from the area. Primary treatment involves physical processes such as sedimentation to remove solids, but does not include biological treatment. Under Polish regulations, plants serving agglomerations of this scale would typically be required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive. However, as Orchowek is now closed, its operational context is historical. The region drains into the Bug River basin, which flows northward into the Narew and eventually the Vistula River, reaching the Baltic Sea. The closure of this facility may have led to wastewater being redirected to other treatment plants in the area.

The plant was located in the Bug River basin, a tributary of the Narew and Vistula rivers, which ultimately discharge into the Baltic Sea. The region supports diverse aquatic life and is part of an important migratory corridor for fish. The closure of the plant reduces local discharge impacts, but any historical effluent would have contributed to nutrient loads in the downstream watershed.
